|Name: ||Reticulocyte, Immature Fraction|
|Reference Range: ||2.4 - 15.0 %|
|Note: ||The Immature Reticulocyte Fraction (IRF) value is an early marker for evaluating the regeneration of erythropoiesis.|
Whereas the IRF percentage increases after only a few hours, the reticulocyte count increases after two to three days.
The IRF is routinely reported with automated reticulocyte counts.
